I am a long time Land Rover owner and have always worked on my own cars, but I am not necessarily the electrical engineer that I need to become to work on this car. But I am undaunted and ready to learn.
I have a new to me 2010 LR4 V8 and I have been having problems with multiple misfire codes on driver’s side bank and a slow coolant leak that I haven’t been able to track down yet. I have been chasing down these codes with a generic BlueDriver bluetooth code reader, but I think I have a larger electrical issue that might be causing contributing to these problems.
It has happened two times to me and when I related the experience to my wife she says it has happened to her as well.
THE PROBLEM:
I was waiting in the truck, not running, for my daughter to come out of basketball. When I went to start the truck, nothing. No dash lights, no navigation screen, no cute little picture of the LR4 on the dash, just complete quiet and darkness. I noticed the brake pedal was really firm gave a hard push on the pedal, pressed the start button again, it made a clunk hesitated and fired up, but with “restricted performance”. Shut truck off. Waited a second. Started as normal with no restricted performance but was stumbling at low rpm. But to my surprise the CEL light is now off, all the codes are gone except for the permanent ones and the clock and date are reset to 2009, as if I had disconnected the battery and discharged the electricity by touching the positive and negative cables together.
Any thoughts?
Bad battery?
Loose ground?
Lucas Prince of Darkness?
The malingering ghosts of Fix On Race Day?
I am retreating for now to the relative calm and clatter of the 300TDI in my Range Rover, awaiting orders from the internet.
P.S I know this is chevy v. Ford territory but suggestions on a better code reader? Also, is there one that will work on both this Land Rover and a BMW X5?
Thanks in advance.
